How to install flash player?

Hi. I would like to install adobe flash player on my knoppix. I hear somewhere i have to find mozilla plugin folder and move there file i get from adobe dot com. I cant find it. I never use that system before

Somehow I'm back to the flash player issue. I was having problems running youtube videos on knoppix version 7.0.5 and decided to wait for the next release. Now I am rRunning knoppix 7.2, Firefox 22, iceweasel 21

Youtube.com says adobe flash player is required. Can't seems to find Flash addon in the FF options. Downloaded install_flash_player_11_linux.i386.tar.gz, extracted libflashpalyer.so and copied it around a few places including:

In my upgraded 7.0.5 knoppix usb to 7.2, I don't seem to have a knoppix menu choice. I think I will create a fresh 7.2 knoppix install before continuing testing for knoppix, firefox and youtube videos. - I'll report back
